CALENDERlNG-MACHINE.

SPECIFIGA'IION forming part of Letters Patent No. 619,107, dated February 7, 1899.

Application filed. September 6, 1898. Serial No. 690,256. (No model.)

To all whom it may concern:

Be it known that I, MYRoN J WHI'ILOCK, a citizen of the United States, residing at Ansonia, county of New Haven, State of Connecticut, have invented a new and useful Calendering-Machine, of which the following is a specification.

My invention relates to calendering-machines of any of the various types in usefor example, paper-calendering machines-and has for its object to provide mechanism by means of which a single operator standing at the base of the machine is enabled to raise both ends of any number of the rolls simultaneously and to lower them to operative position again, thereby adding greatly to the c011- venience of operating the machine and effecting a great saving in the cost of running it.

With these ends in view I have devised the novel mechanism for raising and lowering the rolls, of which the following description, in connection with the accompanying drawings, is a specification, reference characters being used to designate the several parts.

Figure l is an elevation illustrating the application of my invention to a paper-calendering machine, one side of one of the frames being broken away to show the edge of a bearing; and Fig. 2 is an end elevation as seen from the left in Fig. 1, one side of a frame being broken away to show the end of a bearing.

A denotes the frames, which may be of any ordinary or preferred construction and are shown as connected by cross-rods B. The rolls, any number of which may be used, are designated by C,and the beariu gs for the necks E of the rolls'are designated by D. The special shape of the bearings is not of the essence of my invention. It is simply necessary that the bearings be capable of being moved vertically in the frames. In the present instance I have shown the frames as provided with ways rods 1. The upper ends of the threaded rods pass through the top yoke, above which are nuts 5.

6 denotes threaded rods which extend upward from the top yokes and pass through and extend above hubs 7 on the frames.

8 denotes worm-wheels which are mounted to turn on threaded rods 6 and bear upon hubs 7, so that rotation of the worm-wheels will raise or lower the threaded rods and the carriers, of which they comprise a part. Worm-wheels 8 are engaged by worms 9 on a transverseshaft 10, journaled in brackets 11 and 12, which are rigidly secured to the frames. At one end of shaft 10--the left as seen in Fig. l--is abevel gear-wheel13,which is engaged by a bevel-pinion 14 on a shaft 15, one end of which is journaled in bracket 12 and the other in a bracket 16, which is placed at a convenient height from the base of the frame. I have shown the lower end of shaft 15 as provided with a bevel gear-wheel17, which is engaged by a bevel-pinion 18 on a short shaft 19, which is journaled in an extension of bracket 16, shaft 19 being provided with a crank or a hand-wheel 20 for convenience in use.

The operation is as follows: It should be understood that any number of intermediate yokes may be used, depending upon the special use of the machine, each intermediate yoke being supported at each end by a nut 5. Where it is contemplated to raise the rolls in groups, as shown in the drawings, in which intermediate yokes are shown under the necks of the third roll from the top and the sixth roll from the top, no other intermediate yokes are put in in setting up the machine. Should it be likely to be required to raise one, two, or any number of rolls simultaneously, but not in predetermined groups, intermediate yokes would be placed under the necks of each roll, each intermediate yoke resting upon nuts 5. Suppose now that it were desired to raise the first three rolls from the top in a group. The operator would set intermediate yokes close up under both necks of the third roll and then look them in position by turning the nuts 5 up on the threaded rods 1 until they supported the yokes. The operator would then, by turning the hand-wheel, raise both carriers and with them both ends of the entire group of rolls simultaneously and evenly. Should it be desired to raise a group com prising the six upper rolls or any other number of rolls, the operation would be the same, except that intermediate yokes would be set up under the necks of the sixth roll, or the lowest roll in the group to be raised.

I have shown two intermediate yokes only, for the reason that they illustrate the principle of operation as well as more would. In practice, however, it is common to place yokes under the necks of each alternate roll andin some cases under the necks of every roll, so as to avoid the possibility of the necks breaking owing to the enormous weight of the rolls.

Having thus described my invention, I claiml. In a machine of the character described, the combination with a series of rolls and carriers at each end of the machine comprising yokes adapted to engage the necks of any of the rolls, of means for raising both carriers simultaneously so that any number of rolls may be raised or lowered at the convenience of the operator.

. suitable hand-power connections whereby the transverse shaft may be rotated by an operator standing at the,base of the machine.

3. The combination with the rolls, carriers com prisin gyokes adapted to engage the necks the yokes on the carrier and for locking them in position, of transverse shaft 10, vertical shaft 15 and intermediate connections whereby rotation of the vertical shaft is-caused to raise both carriers and any number of rolls simultaneously.

5. The combination with the frames, the 'rolls and the carriers comprising yokes for engaging the necks of the rolls and upwardlyextending threaded rods, of brackets 11 and 12 at the upper ends of the frames and bracket 16 below bracket 12, worm-wheels mounted to turn on the threaded rods, a transverse shaft journaled in brackets 11 and 12, worms and a bevel gear-wheel carried by said transverse shaft, a vertical shaft journaled in brackets 12 and 16, a bevel-pinion carried by the vertical shaft, and means for imparting rotation to the vertical shaft.

In testimony whereof I EtffiX my signature in presence of two witnesses.
